SYSTEM OF IRRIGATION.

SPECIFICATION forming part of Letters Patent No. 346,920, dated August 10, 1886.

Application filed J nly 20, 1885. Serial No. 172,113. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. J nssUr, a citizen of New Jersey, residing at Cinnaniinson, in the county of Burlington and State of New Jersey, haveinvented certain new and useful Improvements in Systems of Irrigation; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. A

Figure 1 is a side view of the device. Fig. 2, a plan; Figs. 3, L, and 5, details.

This invention is an improvement upon a former invention of mine, which is set forth in United States Patent No. 315,629, dated April 14, 1885, to which reference is made for a full understanding of the relation of the two devices.

In the annexed drawings, the letter H indicates the pump; G, the cask into which water is poured to prevent splashing; A, the first trough or section for receiving Water from the cask; O, the secondary conduit; B, the spouts of the main conduit; F, the clampdams, and E the supports, all constructed and to be used as fully set forth in the patent before referred to. In using the device as thus constructed it has been found that where there is a long stretch of level ground the sections are not long enough each in itself, and to use several sections, as described in the patent,with one end closed, such would come too close to the ground. To avoid this and render the device useful both, for long as well as for short levels, I employ auxiliary sections K. These sections are in all particulars like the sections A, except that sections K have both ends 70 open, and not one end closed, as shown at a, section A.

To hold sections A and K together with a water-tight joint, I use an improved clamp, F. This consists of the barf, having the curved barf, faced with rubber, there being an open space between the bars f and f, forming an open clamp, and the bar f hinged t bar f,

and having a curve, f corresponding to the barf, and also faced with rubber. The two bars ff are held by a ring, f. In use the outer open end of section A is placed on one of the ends of the section K, and the two supported by the support E. The ends are then clamped together by the clamp F. '7 of these sections may be provided and used as the length of level may demand. Atthe end of the level and the extended trough thus formed the second section A is to be used, as already set forth in the patent. In like manner I provide auxiliary sections K for the secondary conduit 0, such sections K being in all particulars like sections 0, except that both ends 7f are open. These sections K are used with sections 0 as sections K are with sections A, the clamps F being of a size to fit the sections 0 and K, and auxiliary sections may be made for a tertiary conduit, if such be used.

It is thus obvious that with this improvement the system can be used with ground of any nature. If the levels be short, only one section is used. If they be long, each conduit can be lengthened out by using any number of auxiliary sections.

Having described my invention,whatI claim 1s -1. A system of irrigation consisting of a.

trough, A, having a closed and an open end and spouts along one side, and an auxiliary trough open at both ends and having spouts along one side, as set forth.

2. The clamp F, consisting of the barf and curved bar f, there being an open space between them, and the barf having the curve f, as set forth.

3. In a system of irrigation, the trough A, having one end closed, the other open, and spouts on one'side, and the trough K, having both ends open and spouts on one side, in combination with an open clamp, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE IV. J ESSUP.
